Media is included only with XBW-ARSENIC units. 2

4 Pre-installation Instructions (cont.) Successful Application Any filter media may have specific limitations and/or requirements for successful application. A water sample should be submitted to First Sales for analysis and recommendation by Customer Service. XBW-ARSENIC IMPORTANT: Contact First Sales technical services to assist with proper sizing based on the level of arsenic in the water and the flow rate requirement. The arsenic test results must be from a certified laboratory to ensure accuracy. Other water quality information is required as well, and will determine if pre-treatment equipment is required to meet the influent water quality pre-requisites for the XBW-ARSENIC system: Iron < 0.1 ppm, Manganese < 0.01 ppm, ph < 8.0, Silica < 30 ppm, Hardness > 5 gpg is preferred but not required unless silica is present. Once the system has been installed, an arsenic test should be done to determine if the arsenic level is being reduced sufficiently (10 ppb or less, per the EPA MCL) and should be tested regularly (every 6 months recommended) to ensure the system is functioning properly and to indicate when the media has become exhausted. Time of Backwash Periodically the control valve will go through a backwash cycle. This cycle is factory preset to 12:00 A.M. flushing the accumulated sediment and/or precipitant to the drain. After the backwashing process the unit is now prepared for the next period of service. Water Supply This filter will function properly when the water supply is furnished by a jet pump, submersible pump, variable speed (constant pressure) pump or community water supply. As with all other filter systems, however, it is imperative that the well pump provides enough flow rate for the filter to adequately backwash. In order to ensure sufficient backwash flow rate the following pumping rate test should be performed prior to installing the backwashing filter. 1. Make certain no water is being drawn in the house. 2. Open spigot nearest pressure tank. 3. When well pump starts, close spigot and measure time (in seconds) to refill pressure tank (well pump turns back off). This is Cycle Time. 4. Using a container of known volume, draw water from pressure tank and measure how many gallons until the pump turns back on again. This is Draw Down. 5. Calculate pumping rate by dividing draw down by cycle time and multiplying by 60. Draw Down (gallons) Cycle Time (seconds) X 60 = Pumping Rate (gallons per minute) Example: Draw down is 8 gallons Cycle time is 65 seconds 8 gallons 65 seconds X 60 = 7.4 gpm (gallons per minute) 3

5 Pre-installation Instructions (cont.) Location Considerations The proper location to install the backwashing filter will ensure optimum filter performance and satisfactory water quality. The following factors should be considered in selecting the location of this system. 1. The backwashing filter must be installed after the pressure tank (private well system only). 2. The system should be installed as close as possible (preferably within 15 ) to an adequate floor or laundry drain capable of handling the backwash cycle volume and flow rate (refer to unit specifications). An air gap should be provided between the backwashing filter drain line and plumbing drain. 3. All water conditioning equipment should be installed at least 10 prior to the water heater. Water temperatures exceeding 100 F can damage the internal components of the control valve and filter tank. An expansion tank may need to be installed in the line to the water heater in order to allow for thermal expansion and comply with local plumbing codes. 4. Water pressure must not exceed the range of psi. 5. The system must not be subject to freezing temperatures. 6. The control valve requires 115/120 V, 60 Hz electricity from a three prong outlet that is not wired to a switch. 7. Never install a cartridge type filter prior to the backwashing filter. Any cartridge or in-line filter (if desired) may be installed after the backwashing filter. This will prevent restricting the water flow and pressure available for backwash. 8. Appliances requiring extended periods of continuous or high flow water use (i.e. geothermal heat pumps, swimming pools, lawn irrigation, outside hose bibs, etc.) should bypass the filter. Typical Installation Treated Water Iron Free Hard Water Grounding Strap Untreated Water for geothermal heat pumps, swimming pools, lawn irrigation, hose bibs etc. Expansion Tank Untreated Water Water Heater Softener (If required) XBW, Iron Filter w/ Inlet Coupling XBW-ARSENIC Check Valve (if required for XBW-ARSENIC) Pressure Tank FIGURE 1: Typical Installation 4

6 Detailed Installation Instructions STEP 1: STEP 2: STEP 3: STEP 4: STEP 5: STEP 6: STEP 7: STEP 8: STEP 9: STEP 10: Carefully remove all components from packaging. DO NOT DISCARD PACKAGING until all water filter system components and fittings have been located. -DH suffix models fill media through dome hole & skip to step 4. With the backwashing filter unit in the upright position, remove the control valve from the mineral tank being careful to not pull the distributor out of the gravel at the bottom of the tank. Cover the top of the distributor tube with the included red cap and, using the included blue media funnel, pour filter media(s) into the mineral tank. If using multiple filter media types, load in the order of heaviest (most dense) to lightest (least dense) of space MUST be left empty at the top of the mineral tank to allow for media bed expansion during backwash and to prevent filter media from being discharged through the drain line. Use a garden hose or bucket to fill the media tank with water. Carbon or Filter Ag should soak for at least 2 hours before executing STEP 11 and the other remaining steps. Clean mineral tank (or dome hole) threads to remove any filter media. If -DH suffix model, replace dome plug. Otherwise, remove red cap from distributor tube and reinstall control valve by threading it securely onto the mineral tank. (O-ring seal; HAND TIGHTEN ONLY!) Attach the 90 degree adapters to the inlet and outlet of the control valve (if desired). Hand tighten union nuts. Do not over tighten. Attach bypass valve to the inlet/outlet of control valve or of the 90 degree adapters (if installed). Shut off water at main supply. Relieve pressure by opening nearest faucet. SHUT OFF POWER OR FUEL SUPPLY TO WATER HEATER. Cut main supply line as required to fit plumbing to inlet and outlet of bypass valve. DO NOT PLUMB INLET AND OUTLET BACKWARDS. Piping should be supported. Do not apply heat to any fitting attached to the bypass or control valve. Use the provided polyethylene tubing (NO VINYL TUBING) to run drain line from control valve discharge fitting to floor drain or sump pit capable of handling the backwash rate of the filter. DISCHARGE END OF THE DRAIN LINE MUST BE FIRMLY SECURED! There must be an air gap at the end of the drain line to prevent siphoning of waste water and meet plumbing code. Total length of drain line should be 15 or less. AVOID OVERHEAD DRAINS. Plug the filter into an un-switched electrical outlet. Ensure control valve is in the Service position (time of day is displayed on the screen {refer to page 5 for Home Screen Display}). Place bypass valve in the Bypass position (refer to Figure 2 below). Open main supply valve or turn on power to pump on private well systems. FIGURE 2: Bypass Valve Operation 5

7 Detailed Installation Instructions (continued) STEP 11: STEP 12: STEP 13: STEP 14: STEP 15: STEP 16: Hold down the REGEN button until the motor starts. This will advance the control valve to the backwash position. Once the backwash cycle countdown begins, unplug the power from the control valve to keep it in the backwash position. Rotate the INLET knob of the bypass valve ¼ of the way to Service allowing unit to fill slowly. This will slowly purge trapped air and carbon media fines to the drain. Be patient. When all air and carbon fines have been purged from the system and only water is running to the drain; slowly rotate the inlet knob of the bypass valve to the Service position. Stop momentarily if air or media fines appear in the drain and allow it to clear. Repeat until fully in the service position and then turn the outlet knob to the service position also. Plug the power cable back in. The unit will return to service and display the Home Screen. Check for leaks and correct as necessary. Turn power or fuel supply back on to water heater. Press the SET button to set the current time of day on the timer (note AM and PM). Media Replacement If media replacement is ever required, a wet/dry shop vacuum can used to remove the filter media from the filter tank. CAUTION: There is a layer of gravel under the filter media. Make sure that only filter media is extracted. The filter media should then be replaced by new media. Ensure that there is a minimum of (depending on the type of media) from the media to the top of the tank to allow room for expansion during backwash cycle. The original start up and flushing procedure should be repeated with the new media.
